Having started a fire using Piggy's glasses, it gets out of control and then several boys go missing. Ralph and Piggy try to get the boys to build shelters and follow some basic rules but already the society they are trying to create is breaking down ,the younger boys particularly just want to play and have fun.
Two of the boys, Ralph and Piggy, find a large conch shell and use it like a trumpet to call the other survivors onto the beach.
Jack and a group of choirboys arrive. After discussion Ralph is elected leader and Jack is far from pleased.
Jack is made responsible for organizing a sub-group of hunters. While Piggy is left behind to make a list of all the other boys.
Ralph, Jack and Simon set exploring the island. On the way, they spot a pig. Jack claims he'll kill it for food but couldn't. It becomes clear that no adults survived so the boys have to fend for themselves.
Ralph suggests they build shelter and a signal fire on the mountainside to attract attention. Jack takes over but does so carelessly.
